wATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 726,834, dated Apr128, 1903.

Application filed February 23, 1901. Serial No. 48.533. (No model.)

The apparatus is especially adapted for usein buildings dependent for their water-supply upon reservoirs or tanks located thereupon.

The invention consists in the novel construction and combination of parts hereinaftermorefullydescribed andclaimed,andillus trated in the accompanying drawing, showing the preferred form of my invention, and

which is a vertical section through the apparatus.

Referring to the drawing by numerals of reference, l is a furnace of ordinary construction, and in the combustion chamber or dome(l thereof is arranged a series of coils 3, composed of two adjacent portions standing in vertical planes, one portion of the series being composed of individual horizontal coils,

the lower coil of which extends without the furnace to receive water to be heated, the other portion of the series having vertical iu-` dividual coils, the last one of which is eX- tended upwardly through the furnace and is designed to discharge the heated water.

Located at any suitable point above the furnace l is a tank 4, having a suitable watergage 5 near the top thereof to indicate the amount of water within the tank. A feedpipe 6 opens into the tank and conveys water thereto from a suitable force-pump. (Not shown.) An escape-'pipe 7 is preferably arranged adjacent to the top of the tank, and this permits the escape of all stearn'which may be generated within the apparatus.

Opening into the tank 4 is a cold-water pipe 8, which communicates with the extended end of the lower horizontal coil, and a hot-water pipe 9 extends from the last vertically-extended coil of the vertical series of coils to discharge the heated water into the tank.

Water is forced into the tank 4 from Aa cistern or other supply and passes through the pipe 8, t-he vertical and horizontal coils, and into return-pipe 9. The weight of the Water within the tank and the heat of the furnace will establish a circuit of water through the system, and it is obvious that the hot water discharged from pipe 9 will quickly displace the cold Water drawn off through the pipe 8. Suitable pipes (not shown) may extend from the. tank 4, and in thismanner hot water `may be distributed as desired.

By employing a-pipe formed-in parallel series of coils, `the coils of one series extending transversely of the coils of the remaining series, a number of coils may be com pactly arranged within au inclosure and the resistance to .ithe .passage of water therethrough decreased, whereby the water is heated more rapidly and thoroughly.

In the foregoing description I have shown Vwhat I believe the best form of invention; lbut I do notlimit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any advantages thereof, and therefore reserve the right to make all such changes as fairly fall within the scope of my invention.,

I claimj l Ina water-heating system, the combination with the furnace, of a series of coils in the combustionchamber, said coils composed of two adjacent portions standing in vertical planes, one portion of the series composed of individual horizontal. coils, the lower coil of which extends to without the furnace to receive water to be heated, the other portion ofthe series having vertical individual coils,

.the last one-.offwhich is extended upwardly through thefurnace to discharge the heated water, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
